Description Huzaifa S. Sidhpurwala 2012-10-11 02:39:34 EDT 
Mozilla developers identified and fixed two top crashing bugs in the browser engine used in Firefox and other Mozilla-based products. These bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

The first of these bugs, a FreeType issue, is a mobile only issue which happens on custom kernels like Cyanogenmod, not on standard Android installation. The second bug is a websockets crash affecting Firefox 16 but not Firefox ESR.

This bug is used to track the second issue (CVE-2012-4191) which does not affect Firefox ESR.
